if the dog's owner is a Chinese, they need to know, either Hokkien, Hakka, Cantonese, or mandarin.
if the dog's owner is malay, they need to understand malay.
How about if the dog's owner is an indian, of course, they need to understand tamil!!! ah------ne!:)
My indian neighbour has a dog, called brownie.
Brownie barks a lot, and i actually very beh tahan. but brownie will stop barking when his owner don't know shout what thing.!:))
next time when a dog chase you, you gotta be watch out! Is no use if he don't understand "NO". try other language looo :P goodluck
